THREAD-GUIDE FOR SHUTTLES.

Specification of Letters Patent.

Patented Uct. 29,1918.

Application filed January 25, 1918. S eria1No. 213,762.

To all whom it may concern:

Be it known that I, FREEMAN CASS, a citizen of the United States,residing at Brooklyn, county of Kings, State of New York, have inventedcertain new and useful Improvements in Thread-Guides for Shuttles, ofwhich the following is a specification.

The'present invention relates to improveguiding eyes for loom shuttlesand particularly is an improvement upon a device for this purpose of thetype or general character illustrated patent to J. R. Mitchell, No.1,188,005, dated June 20, 1916.

The object of the present invention is to provide a thread tension orguiding eye. having a bodyof porcelain, or similar matemetal cap orholder, which may be readily connected with or detached from the poroesecure the same properly in the shuttle.

In the accompanying drawings Figure 1 isa plan view of a portion of aloom shuttle provided with a thread guide embodying the invention;

Fig. 2 is a sectional view, on the line 2-2 of Fig. 1;

Fig. 3 is a longitudinal sectional view through the thread guide,detached from the shuttle;

Fig. 4 is an end view of the guide;

Fig. 5 is a sectional view, on the line 5-5' of Fig. 3, drawn to anenlarged scale;

.Fig. 6 illustrates a slightly modified form of the cap or head.

Fig. 7 is a perspective view of the device shown in Fig. 6; and Fig. 8is a detail sectional view.

Referring to the drawing A designates the loom shuttle, provided withthe slots and openings commonly used in self threading shuttles and inwhich is-suitably positioned.

the thread tension and guiding eye constituting the present invention.

This, as shown, comprises a body, B, of any suitable vitreous material,such as porcelain, glass, etc., hereinafter referred to as porcelain,and a metal head or cap, (1, which'is detachably connected to the bodyand provided with means for engaging the shuttle to retain the guide inproperposition therein. The body B is provided with the usual slots andeyes including the thread rer1al, for contact with the thread, with a.

ceiving opening, 6, and as shown the cap or head, C, receives the end ofthe body which is solid and does not extend beyond the said opening 6.

The cap or head, C, is held from relative rotary movement on theporcelain body by means on its inner surface engaging said body, as byforming a rib or lug C on the interior of the cap which fits within asuitably formed recess or groove in the body B. The cap and body arefurther united, and held from separation, by a screw D, or equivalentfastening means, so that the two form a unitary structure which can bereadily fitted to or removed from the shuttle A.

Exteri0rly the cap or head C is provided with means for engaging thebody of the shuttle and holding the guiding eye-in position therein. Inthe form of the invention illustrated in Figs. 1 to 5 this meansconsists of a rib or lug c which is adapted to enter a suitable grooveor socket in the shuttle to hold the guiding eye from rotation therein.

As shown in Figs. 6 and 7 the metal head or cap member G of the guidingeye may be provided with a plurality of exterior ribs or lugs, E, toincrease the extent of engagement between it and the shuttle.

The manner of using the improvements and the advantages thereof will bereadily apparent.

It will be seen that the invention provides a thread guiding eye inwhich the thread contacting body is of porcelain, which material hasbeen found most suitable for such purpose, while the shuttle engagingportion is of metal so that it will accommodate itself to contraction ofthe wood of the shuttle, Without causing breakage of the porcelain body.Further the cap or head can be readily removed and a new onesubstituted, or the same cap or head may be used successively with aplurality of porcelain bodies.

Instead of employing a screw D to con nect the metal cap or head withthebody B a pin or other equivalent securing means may be employed, asshown in Fig. 8.

Having thus described the invention, what is claimed and desired to besecured by Let ters Patent is 1. A thread guiding bushing for a shuttlecomprising a porcelain body, a metal head fitted on one end of the bodyand provided with an exterior rib adapted to engage the shuttle toprevent rotation therein of the ment by an interlocking rib and grooveand bushing, and means connecting the head and said head beingexteriorly provided with body to prevent separation thereof. means forengaging a shuttle, and means for 10 2. A thread guiding bushing for ashuttle securing the head to the body to prevent 5 comprising aporcelain body, a metal head separation thereof.

fitted to one end of the body, the head and In testimony whereof I aflixmy signature. body being held from relative rotary move- FREEMAN CASS,
